Direct ortho-arylation of 2-arylbenzoxazoles via C-H activation

Yang, Fan,Wu, Yangjie,Zhu, Zhiwu,Zhang, Junli,Li, Yanan

, p. 6782 - 6787 (2008/12/20)

A new and highly regioselective arylation of 2-arylbenzoxazoles based on C-H activation has been developed. The results represent the first examples of palladium-catalyzed direct ortho-arylation of 2-arylbenzoxazoles and also provide a facile route for the synthesis of complicated structures containing arylated benzoxazoles moieties.
